Convert the format of `pip list` to requirements.txt file

pip_list_to_requirements.py

"""
  Sometimes when you run `pip freeze > requirements.txt` when using a conda environment, 
  it spits out the exact locations of the packages on the local machine.
  
  This script allows you to run `pip list` instead, and 
  convert the output of `pip list` into the format used by `requirements.txt` files.
